Trailer Axles
TRAILER AXLESdco axles are manufactured from the finest quality C1040 hot rolled steel When greater strength is required due to excessive overhang axles c
de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

MIL-M-8090 requires the drawbar to be raised at any possible cramping or turning angle of the tongue

Trailer Axles
TRAILER AXLESdco axles are manufactured from the finest quality C1040 hot rolled steel When greater strength is required due to excessive overhang axles c
de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

Trailer Axles
TRAILER AXLESdco axles are manufactured from the finest quality C1040 hot rolled steel When greater strength is required due to excessive overhang axles c
de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

Trailer Axles
TRAILER AXLESdco axles are manufactured from the finest quality C1040 hot rolled steel When greater strength is required due to excessive overhang axles c
de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

Trailer Axles
TRAILER AXLESdco axles are manufactured from the finest quality C1040 hot rolled steel When greater strength is required due to excessive overhang axles c
de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

Trailer Axles
TRAILER AXLESdco axles are manufactured from the finest quality C1040 hot rolled steel When greater strength is required due to excessive overhang axles c
de on special order from 4140 hot rolled alloy steel Axle spindle dimensions are shown in hub series section Axle capacity cannot exceed the
ndle capacity All axles are furnished complete with spindle nuts washers and cotter pins and Z rings where required
DROP
dco axles 2amp14 square or less may be manufactured with 2 3 4 5 and 6 inch drop
APACITY
axle and axle component capacities are based upon gross load measured at the ground
AMBER
Hadco straight axles over 70 inches long (2amp14 sq or less) will be cambered 1amp12deg (Nominal) at center unless otherwise requested Steerin
es are cambered 1amp12deg (Nominal) at the spindle All dropped axles are cambered 1amp12deg (Nominal) at the drop
RACK
ck is the distance in inches from tire centerline to tire centerline on axle assemblies with single tires On duals track is measured at the centerlween the dual tires
RACK VS AXLE LENGTH
A = distance from outside of hub flange to end of axle in inches (See drawings on hub series pages
for this dimension)
ish= the distance between the centerline of the tire and the hub face in inches (May be positive or
negative Positive dish is shown at right) (See wheel charts for this dimension)
fference between track and axle length
= 2A + 2 Dish (positive dished wheels)
= 2A - 2 Dish (negative dished wheels)
fference between track and axle length is shown in hub series charts
RACK VS OUTSIDE TIRE WIDTH
side tire width of axle assemblies with single tires is track plus the width of one tire plus one (1) inch allowance for camber
VERHANG
erhang for axles with single tires is the distance from the centerline of the spring to the centerline of the tire
erhang for axles with dual tires is the distance from the centerline of the spring to the centerline of the duals
VERHANG VS AXLE CAPACITY
e beam carrying capacity is reduced as the overhang is increased See Axle Beam Capacity Chart

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter

afety Information
IMPORTANT SAFETY INFORMATIONHADCO products are designed with a margin of safety that years of analysis and experience has shown tobe more than adequate for their rated capacities in the service specified Operation at higher-than-ratedspeeds or on a terrain or in a service other than specified overloading using mismatched components oexcessive axle overhang neglecting to maintain correct tire inflation or the recommended lubricationfrequency can cause sudden failures with possible serious consequences
We recommend that maximum speed and payload correct tire inflation pressure wheel bolt (lug nut) torque and
bearing maintenance information be displayed along with other safety information in a conspicuous place on thecompleted vehicle
Care should be taken to assure equal side-to-side loading
Designers not familiar with factors influencing the stability of towed vehicles (especially at high speed) should contact
Hadco Engineering early in the design stage since this stability is dependent on chassis dimensions and weight
distribution Anticipated extremes of terrain or operating conditions must be brought to the attention of Hadcos
Engineering Department
HOW TO DETERMINE CAPACITIES
Capacity in all cases refers to the load measured at the ground
ASSEMBLIES
In assembling running gear components it is desirable to match the capacities of the axle tires wheels brakes etc as
closely as possible The component with the lowest capacity determines the capacity of the entire running gear For
example if an axle beam rated at 5800 Ibs is matched with wheels rated at 2600 Ibs each (5200 Ibsaxle) tires at
5100 Ibs and brakes at 5000 Ibs then the axle assembly capacity is rated for 5000 Ibs If you select larger capacity
brakes say 5200 Ibs the axle capacity is then rated by the next lowest capacity component (the tires) at 5100 Ibs
COMPONENTS
All load carrying components and brakes in this catalog have rated capacities at given speeds Some components are
rated for low speed service only on specified surfaces Except where so noted capacity of components is given at
highway speeds nominally 55 mph For low speed service ON PAVED SURFACES WHEEL HUB and AXLE
capacities may be increased CONSULT HADCO ENGINEERING DEPT
TIRES may not exceed the ratings shown in the tire capacity charts Individual tire manufacturers ratings may vary
slightly from the values shown and should be used when known Tire inflation pressure must not exceed the inflation
pressure shown for the wheel on which it is to be mounted
BRAKE ratings are not to be exceeded regardless of speed without approval of Hadcos EngineeringDepartment
SPRING capacities remain constant regardless of speed
WHEEL BOLT (LUG NUT) TORQUELug nuts should be re-torqued after the first 100 miles of operation and checked periodically thereafter
